Method Detail

hasUseGlop

boolean hasUseGlop()

 If true runs Glop's presolver on the given instance prior to solving.
 Note that convergence criteria are still interpreted with respect to the
 original problem. Certificates may not be available if presolve detects
 infeasibility. Glop's presolver cannot apply to problems with quadratic
 objectives or problems with more than 2^31 variables or constraints. It's
 often beneficial to enable the presolver, especially on medium-sized
 problems. At some larger scales, the presolver can become a serial
 bottleneck.
 

optional bool use_glop = 1;

Returns:

Whether the useGlop field is set.

getUseGlop

boolean getUseGlop()

 If true runs Glop's presolver on the given instance prior to solving.
 Note that convergence criteria are still interpreted with respect to the
 original problem. Certificates may not be available if presolve detects
 infeasibility. Glop's presolver cannot apply to problems with quadratic
 objectives or problems with more than 2^31 variables or constraints. It's

 problems. At some larger scales, the presolver can become a serial
 bottleneck.
 

optional bool use_glop = 1;

Returns:

The useGlop.

hasGlopParameters

boolean hasGlopParameters()

 Parameters to control glop's presolver. Only used when use_glop is true.
 These are merged with and override PDLP's defaults.
 

optional .operations_research.glop.GlopParameters glop_parameters = 2;

Returns:

Whether the glopParameters field is set.

getGlopParameters

GlopParameters getGlopParameters()

 Parameters to control glop's presolver. Only used when use_glop is true.
 These are merged with and override PDLP's defaults.
 

optional .operations_research.glop.GlopParameters glop_parameters = 2;

Returns:

The glopParameters.

getGlopParametersOrBuilder

GlopParametersOrBuilder getGlopParametersOrBuilder()

 Parameters to control glop's presolver. Only used when use_glop is true.
 These are merged with and override PDLP's defaults.
 

optional .operations_research.glop.GlopParameters glop_parameters = 2;
